As far as I know, at the moment it is only the Windows Gimp 2.10.6 from gimp.org that contains those debug files. Samj has a portable Gimp 2.10.6 but contains none of the files.
I ran a couple through virustotal online scanner, all good results, including comodo

I would say (as far as anything is certain with M$) your home virus scanner is showing false positives.
Edit: Apologies, I was looking at the wrong samj version and the 2.10.6 portable does flag up those debug files.
However, on balance, I still think these will be false positives. Not unknown for 'heuristic' scanning.
